z claims. (c1. 31a- 214) invention relates to a domestic appliance, and more particularly to a compartment provided with a horizontally movable shelf which may be located at different levels inthe compartment and which is pulled out by the opening of the doors.

It is an object of this invention to provide an arrangement wherein a movable ball bearing type shelf may be placed at a` plurality of diiferent levels within a compartment and to provide an easily removable attachment by which the shelf may be pulled out of the compartment horizontally whenever the door or doors of the compartment is or are opened.

This and other objects are attained in the form shown in the drawings in which an oven compartment is provided with a plurality of shelf supports capable of supporting a horizontally movable shelf. The compartment is provided with double French type doors linked to a common traveler beneath the compartment. A rod extending beneath the compartment is provided with a def tachable bayonet connection with the traveler. The rod is provided with an arm extending into the door opening and having a plurality of connecting links and attachfing clips which form a removable attachment to the front edge of the shelf. The opening of the doors moves the traveler, the rod, the arm, the links forwardly and the shelf. also forwardly out of the compartment while clos- `ing of the doors moves the shelf back into the compartment..

2 downwardly extending projection 32 at an intermediate point as is disclosed in Figure 4. l

Within the compartment 28 there is provided a Ihorig zontally movable shelf 34 having a rod extending around its'perimeter and bars extending horizontally from front to -rear between the rfront and rear portions of the rod.

The sides of the rod of the shelf 34 are each provided with a channel shaped ball race 36 which extends between the upper and lower sets of balls 38 and 40 which are retained in the cage 42. The balls roll within a channel shaped outer race 44 which is supported upon the upper shelf guides 30 as shown in full lines in Figure 3 or upon the lower shelf guides 46 as suggested by the dot-dash lines. The channel 44 has a Z projection 48 welded to it which extends beneath the shelf guide 30 immediate'elfy in front of the projection 32. These projections 48 limit 4the rearward movement of the channel member 44 and pivotally connected by a pivot pin 52 to the upper an'ge a preferred form of the present invention is clearly shown; f 1

Figure 7 is a perspective view of the traveler, rod, arm and links.

Referring now to the drawings and more particularly to Figure 1, there is shown a domestic electric range 20 including a range top 22 extending over and down to the double doors 24 and 26 which close the door opening to the oven compartment 28 enclosed by the walls forming the oven compartment. The side walls of the oven compartment 28 are provided with a plurality of spaced shelf guides 30 each of which is provided with a of the channel 44. This latch member 50 includes a pin r54 extending in opposite directions and having one end protruding outwardly so that the projection 56 of the shelf guide 58 immediately above interferes with its free outward movement whenever the channel 44 is withdrawn forwardly. The member 50 has its center of mass to the rear of the pivot pin 52. so that the pin 54 is normally held in its uppermost position. When it is desired to withdraw the channel 44 the inner ends of the pins 54 are pushed downwardly to allow them -to pass the projection 56.

The double doors are hinged at their outer edges. The bottom of each door is connected by one of the links 60 to a pin 62 in the form of a projection extending downwardly from an upper traveler 64. This upper traveler 64 is preferably made of nylon. There is also a lower traveler 66 beneath the links 60 provided with an aperture receiving the pin 62. This lower traveler 66 likewise made of nylon and has a grooved` center portion. The top of the portion 64 is a frustro-cylin drical surface. These contours for `the travelers 64 and 66 make it possible for them to slide easily within the guiding housing 68 which is located beneath the oven compartment upon the -bottom surface ofthe bottom Wall of the oven compartment. The guideway 68 is provided with side slots 70 through which extend the links 60. The rearY ends of the links 60 with camming projections which cooperate with the spring latch retaining members 7,2" located on each side at' the rear end of the guideway 68.v This arrangement provides a resilient latch holding both'doors in the closed position.` The opening of either door nwill cause 4the simultaneous opening of the other door.

According to my invention, I provide a detachable connection4 between rthe traveler 64 and the front edge of the shelf 34. The traveler 64 is provided rwith a bore or vsocket 74 having diammetrically opposite grooves in the sides thereof. The bore 74 at its front end is counter'- s'unk. This makes it possible to readily insert into the Y bore 74 the bayonet connection 76 having a cross bar 78 atits inner end which is guided in the slots in the bore 74. The remainder of the bayonet connection 76 is cylindrical and terminates in a beveled shoulder 80 which limits the inward movement of the bayonet con nection at the rear end of the rod 82. The rod 82 extends forwardly through the guideway 68 and through an aperture 84 in the downwardly extending portion 86 extending downwardly from the front edge of the bottom wall of the oven compartment 28.

In front of the flange 86, the rod 82 has fixed to it an arm 88 in the form of a metal strap which extends up wardly between the doors and the ange 86 when the doors are closed. The flange 86 preferably is provided with a vertical groove or depression extending upwardly lfrom the aperture 84 to receiverthe arm 88. The upper end of the arm 88 is offset inwardly above the bottom wall of the compartment 28. At its upper end this arm 88 has two links 90 and 92 pivotally connected to it. Pivotally connected to the opposite ends of these links 90 and 92 are the connectors 94 and 96 each ofY which are provided with an upper inverted U-shaped detachable connecting portion which hooks over the front portion of the rod which forms the perimeter of the Ashelf 34 as is clearly shown in Figures 1 and 2.

By this arrangement the opening of either door will simultaneously open the other door and pull the travelers 6'4 and 66 forwardly. The forward movement of the travelers 64 and 66 will move the rod 82, the arm 88, the

Vrasaaars 4 movable traveler outside said walls below and separate from said shelf, a horizontal guide means outside said walls for guiding said traveler horizontally along the outside of one of said walls, links connecting each of said doors with said traveler, a ange extending outwardly from said one wall adjacent said door opening, said flange having an aperture therein, a horizontal rod extending through said aperture and provided adjacent one end with a rotatable detachable connection with said traveler, said rod extending within and substantially parallel to said horizontal guide means, the opposite end of said rod being provided with a radially extending rigid arm in front of said flange extending into said door opening,

links 90 and 92, the connectors 94 and 96 and the shelf position of the shelf the links 90 and 92 extend upwardly at an angle of about 45. In either position the connectors 94 and 96 provide a rm connection with the perimeter rod at the front edge of the shelf 34.

If it is desired not to have the shelf 34 move outwardly with the opening of the doors, the connectors 94 and 96 are lifted oi the perimeter rod at the front edge of 'the shelf 34 and the arm 88 and the rod 82 is turned 90 to the position shown in Figure 7 aligning the cross bar 78 with the grooves or notches in the bore 74 and then withdrawing the assembly forwardly to detach the A rod 82 from the traveler 64. The rod 82 and the connected arm 88 and links 90 and 92 are then removed from the range, thereby preventing the shelf`34 from being moved whenever the doors are opened.

The shelf 34 continues to be useful as a ball bearing supported shelf which is readily movable horizontally. The shelf 34 with the channels 44 can be readily removed or changed in position by pulling the assembly outwardly and depressing the pins 54 to pass projections 56 or 32. The channels 44 are connected by front and rear cross bars 98 as shown in Figures 3 and 4. The shelf 34 and the channels 44 may be replaced by a reverse procedure. The shelf 34 may be reconnected to the traveler 64 by reinserting the rod 82 into the traveler 64 and turning it 90 to complete the bayonet type connection and reconnecting the connectors 94 and 96 to the shelf 34 in either its upper or lower positions.

This application is a continuation-in-part of my copending application Serial No. 365,142, led June 30, 1953, which issued on June 19, 1956, as Patent 2,751,486.
